Can bed bug live on animals?

No. unlike fleas bedbugs infest beds not people or animals. The bedbug detects the breath of any person near to it sleeping. The bedbug homes in on where the sleeping human's breath is coming from to find its food, which is human blood. After its meal the bedbug will usually set up its base in or near the bed and females lay eggs near to or in the bed so new bedbugs get born and so the bed becomes more and more infested. Bedbugs do not normally bite animals nor are they attracted to pets or to the bed of pets.
